Abstract: ABSTRACT OF THE DISCLOSURE A disc drive is disclosed for positioning magnetic heads relative to a disc having radially spaced data tracks.  The disc drive includes a motor, a drive shaft coupled to the motor and driving the carriage for radial positioning.  A stationary sensor and stop assembly is mounted in the disc drive in a fixed position relative to the  movable carriage.  A moving crash stop and zero track interrupter is mounted on the drive shaft for rotation with the drive shaft.  This includes fixed stop means for striking the stationary sensor and stop assembly in both directions of rotation;  the crash stop and zero track interrupter activates the sensor and stops rotation in a first direction of rotation of the motor drive shaft corresponding to a first direction of movement of the carriage.  The assembly strikes the sensor in a second direction of rotation to establish a limited movement in the second direction of rotation corresponding to the  second direction of move-ment of the magnetic heads.  As a result of this assembly, the limits of movement of the carriage in both directions of travel are defined by a single integrated assembly which rotates with the same drive shaft which is moving the carriage.

Abstract: Abstract of the Disclosure One embodiment of an invention providing an improve-ment upon a U-bolt bender is disclosed.  The bender has a clamp for clamping a workpiece thereto and a slide for advancing the workpiece along a path.  The improvement comprises a die and biasing means for urging an intermediate portion of the workpiece against a forward surface of the die and for urging end portions of the workpiece respectively against sides of the die adjacent to the forward surface.          The bender carries the biasing means and the slide carries the die and brings the workpiece into engage-ment with the biasing means by advancing the workpiece along the path.  The sides of the die converge to-gether and extend away from the forward surface such that as the slide brings the workpiece into engage-ment with the biasing means, the biasing means urges the intermediate portion of the workpiece against the forward surface and urges the end portions of the workpiece respectively against the sides of the die, the slide meanwhile causing the clamp to clamp the workpiece to the die.  The workpiece initially con-forms to the shape of the die; and is made of a re-silient material; and upon being released from the die and the biasing means, has end portions which spread apart slightly.  The sides of the die are oriented such that the workpiece, upon being released from the die and the biasing means, has end portions which are in substantially parallel orientation, one end portion to the other.

Abstract: ABSTRACT OF THE DISCLOSURE     A sandwiching machine is disclosed providing equal filler flow rates to nozzles in a rotational stencil and regular flow regardless of the speed of displacement of an associated conveyor passing by upstream and downstream cookie supply stations and a filler depositing station therebetween,the filler flow rate being regulated as a function of the speed of displacement of the conveyor, The machine provides synchronization of the rotational speed of the rotational drives for the conveyor chains by means of a mechanical connection comprising clutches associated with a speed change device. The pressure of filler at the admission sides of volumetric pumps is maintained constant by means of a pressure regulator and accumulator, The feeding of the stencil cylinder is effected through two separate inlets. One inlet feeds filler into a hollow shaft fixed to the body of a valve member through a radialchannel for communication through ports in the stencil cylinder with orifices in the rotational stencil, The other inlet carries filler into the delivery box at one end of the stencil cylinder between the latter and the hollow  shaft. The ports may be selec tively closed off by angular movement of the valve member.

Abstract: Noble Metal Catalyzed Reactions Abstract A method is disclosed for improving the performance of noble metal catalysts such as platinum in catalyzed chemical reactions where the reduction of oxygen is a rate limiting step.  The catalytic activity of the catalyst and thus, the rate of reaction is increased by increasing the electron density of state at the Fermi level of the catalyst.  This can be accomplished, for example, by alloying the noble metal catalyst with materials which increase the electron density of state.

Abstract: ABSTRACT OF THE DISCLOSURE      During the process of vacuum deposition, metals and materials are evaporated at a point source so as to create a vapor which is dispersed  isotropically.  Layers of the evaporating material are deposited as built-up layers which have sharp vertical edges or steps at the areas defined by the photoresist stencil.  When the line of sight of the depositing material is from an oblique angle, the layer being deposited can have a negative slope which appears as an undercut edge.  The present invention employs a lift-off overhang photoresist stencil in conjunction with a relatively high pressure of inert gas in the vacuum chamber so as to promote collision of the evaporated atoms and molecules with the inert gas.  The colliding atoms and molecules of the evaporating material no longer appear to be originating from a point source but appear to originate from an extended area in the end of the vacuum chamber and deposit under the overhang photoresist stencil so as to provide symmetrical positive slope step changes at the edges of the material being deposited.

Abstract: ABSTRACT  There are disclosed a process for producing (-)-5-(R)-1-hydroxy-2-[(R)-1-methyl-3-phenylpropyl amino-ethyl salicylamide and its acid addition salts in high yields which does not require chromatography, and impor-tant intermediates in this process.  The process is stereoselective for the desired (R,R) amine; a preferred embodiment includes the steps of (1) reaction of an N-[(R)-protected]-(R)-1-methyl-3-phenyl-propylamine with a 4-0-protected 2-bromo-3-carbamoyl-ace-tophenone to produce the corresponding R,R-glycyl-benza-mide, (2) reduction to produce a mixture of S,R,R;R,R,R--hydroxybenzamides, (3) removal of the protecting groups, (4) resolution of the deprotected product and, if de-sired, conversion to the free R,R -amine or to another salt.  In this process, the selection of particular N-pro-tecting groups has a very favourable effect, especially in steps (2) and (3).
